Please launch the attached snippet on Windows (tried Windows 10) and Linux (tried latest Antergos). It should show a dialog shell on top of a top-level shell. On Windows, you will see just one line of output:

Got SWT.Show

but on Linux you will see an endless list of

Got SWT.Show
Got SWT.Show
Got SWT.Show
Got SWT.Show
Got SWT.Show
Got SWT.Show
Got SWT.Show
Got SWT.Show
Got SWT.Show
...

followed by some critical messages
